You enter the form 1099-R for the QCD as any other form 1099-R as the form 1099-R bears no indication that it is a QCD.
If you are aged over 70 1/2 and the distribution is from an IRA (the box next box 7 is checked), then in the follow-up interview, TurboTax will ask you if the distribution is a QCD. If so, answer YES to the question. TurboTax will exclude it from taxation.
